Title: Method of flame spraying thermoplastic resins
IPC: B05B7/14
Filed: 1951-08-20
Abstract: In a method of flame-spraying upon a surface, a stream of thermoplastic resin in powder form is projected through a flame spray gun (see Group XXIX) in which an annular stream of a non-combustible cooling gas is interposed between the flame and powder stream, and the flow velocities of the cooling gas, powder stream and combustion gases are so correlated that fusion of the powder stream occurs predominantly upon its impingement on the said surface.  The surface is heated prior to the application of the powder by the flame of the gun by shutting off the powder stream and reducing the cooling gas flow.  The flow of the powder and of the gases through the gun is controlled by valves.

Filed: 1975-05-12
Abstract: 1511322 Printers CASIO COMPUTER CO Ltd 12 May 1975 [13 May 1974] 19906/75 Heading G4H A printer prints (at 16) unit records, each comprising a plurality of numbers, from memory device 11, in a corresponding plurality of columns under control of column width data from an auxiliary memory 31, 32 previously loaded by counting (at 37) the number of digits in each number in memory device 11 and comparing the count (at 35) with the "maximum width required for this column so far" read from auxiliary memory 31, 32, the count replacing this stored maximum value if the count is bigger than it, so that auxiliary memory 31, 32 eventually holds the maximum width required for each column. The counter 37 starts from a count of one in each case to give a gap of one character between columns on print out. Memory device 11 supplies its contents for printing at 16 via an n-digit memory device 13: once a number has been loaded into the right-hand-end of this device 13, it is shifted out to 16 with decrementing of counter 37 from an initial count of n, "print instruction signals" (to cause printing and stepping from one character position to the next) being sent to 16 from the point at which the count at 37 equals (at 35) the respective column width from 31, 32, so each number is right-justified in its column. In memory device 11, the unit records are separated by code BE and the numbers are separated by code BK, which codes are detected at 51 for control purposes. Non-numeric data is also printed, being detected at 19 and supplied to 16 via 17 (from 13).

Title: Electric circuit breakers embodying electromagnetic release means
IPC: H01H71/74
Filed: 1960-06-08
Abstract: 886,267. Automatic circuit-breakers. WESTINGHOUSE ELECTRIC CORPORATION. June 8, 1960 [June 10, 1959], No. 20089/60. Class 38 (5). To set the instantaneous tripping current of a circuit-breaker having electromagnetic tripping means, the position of the armature 99 relative to the yoke 95 is adjusted by a pivoted lever 119 having calibrating means, e.g. a screw 135, at one end engaging the armature 99. The other end 129 of the lever 119 engages a face cam 121 carried by a shaft 143 rotatable in brackets 139, 141 which prevent axial movement of the shaft and cam. An adjusting knob 142 on the shaft 143 has a notched flange 144 biased against the bracket 141 by a spring 149 between the knob and the shaft, the notches 151 co-operating with a detent 153 to index the knob, shaft and cam. The armature 99 has a pivot 101 bearing in a notch 102 on one leg of the yoke 95, the other leg of the yoke having its outer laminations extended to form auxiliary polepieces 115 which, when the electromagnet is energized provide a backward pull on the armature. By turning the knob 142, the cam 121 causes the lever 119 to pivot and move the free end of the armature away from the auxiliary polepieces 115 and nearer to the yoke 95 to reduce the current setting. When the armature is attracted to the yoke 95 under heavy overload conditions, the head 105 of a rod 103 secured to the armature 99, engages and turns a pivoted trip bar 81 so that a latch 91 on the trip bar releases the circuit-breaker latch mechanism 93. Under smaller overload conditions, the trip-bar 81 may be operated by a bimetallic strip 45 which engages a calibrating screw 109 in the trip bar 81. A terminal strip 17 forms the winding for the electromagnet and the heater for the bimetallic strip.

Title: Improvements in and relating to the treatment of surfaces
Inventor: GATES WILLIAM ELLIOTT FREW
IPC: C08J7/12
Filed: 1953-07-13
Abstract: Polyethylene surfaces, e.g. films or coatings, sheets, tubes and moulded articles, maintained at a temperature not less than 50 DEG C. and exposed to ozone have improved bonding properties, particularly to printing inks.  Ozonized air, containing 3 to 8 per cent ozone, obtained for example by passing air through a silent electric discharge may be used, and the polyethylene heated, preferably not above softening temperature either before or simultaneously with the exposure.  In an example a film of polyethylene is passed continuously downward through valves in a chamber heated by infrared rays through glass panels, while ozonized air at 80 DEG  C. is passed upwards.  The film is then cooled on rollers and printed with gravure type ink.  Specifications 738,474 and 758,461 are referred to.

Title: Steroid intermediates for the preparation of adreno-cortical hormones
Inventor: CALLOW ROBERT KENNETH
IPC: C07J75/00
Filed: 1955-07-13
Abstract: The invention comprises compounds of the general formula <FORM:0805497/IV (b)/1> wherein X represents an acyl group or hydrogen, and R represents hydrogen or a halogen, and a process for the preparation of 17a -hydroxy-16-halo - 9(11) - ene - 20 - ones of the pregnane and allopregnane series by oxidizing steroid 9(11) : 16 - diene - 20 - ones of the pregnane and allopregnane series to form the corresponding 16 : 17 - oxido - 9(11) - ene - 20 - one compounds and reacting the 16 : 17 - oxido compounds with a hydrohalic acid, e.g. hydrobromic acid.  The oxidation step may be carried out with alkaline hydrogen peroxide.  A suitable reactant for the above process is a 3 - acyl - allopregna - 9(11) : 16 - diene - 3b -ol-20-one.  The above process may be extended to include the additional step of removing the 16-halogen atom by hydrogenolysis, e.g. by treating the 16-halo compound with Raney nickel, to form 17a -hydroxy-9(11)-ene-20-ones of the pregnane and allopregnane series. These compounds may then add on the elements of a hypohalous acid to form a 9a -halo-11-hydroxy compound, e.g. by treating the compounds with an N-haloacylamide or an N-haloacylimide in the presence of a strong acid such as perchloric acid, and the 11-hydroxy compound may then be oxidized with a strong oxidizing agent containing hexavalent chromium, e.g. chromium trioxide.  In the example, allopregna-9(11) : 16-diene - 3b  - ol - 20 - one 3 - acetate is treated with hydrogen peroxide and sodium hydroxide, and the resulting allopregn-9(11)-en-3b -ol-20-one-16a  : 17a -epoxide acetate is treated with hydrobromic acid to form 16-bromo-allopregn-9(11) - ene - 3b  : 17a  - diol - 20 - one 3 - acetate.  Subsequent treatment with Raney nickel forms allopregn - 9(11) - ene - 3b  : 17a  - diol - 20 - one 3-acetate.  The Provisional Specification refers to compounds of the above general formula wherein R represents bromine, chlorine, iodine or hydrogen and X has the above significance. Specification 750,799 is referred to in the Provisional Specification.
